摘　　要：利用金属橡胶制备一种波纹夹芯板,通过试验和有限元分别研究结构的宏观及微观力学特性,为加快计算速率,构建有限元等效模型研究不同材料参数对结构力学性能的影响,并进行试验验证。结果表明,金属橡胶波纹夹芯板受载条件下会存在两个阶段:平台阶段与致密阶段,相较于传统波纹夹芯板,其平台阶段加长且吸能效果提高。结合试验和有限元发现导致这两个阶段的原因是,结构在受载条件下会存在极限载荷致使夹芯层屈曲变形从而使结构内部空隙减少,结构进一步受载达到致密阶段。通过两者的对比验证了研究结果的有效性,为金属橡胶波纹夹层板的未来设计和应用提供了指导。Acorrugated sandwich plate was prepared by metal rubber,and the macro and micro mechanical properties of the structure were studied by experiment and finite element respectively.In order to accelerate the calculation rate,the finite element equivalent model was established,and the influence of different material parameters on the mechanical properties of the structure was studied and verified by experiment.The results show that there are two stages under load:platform stage and compact stage.Compared with traditional corrugated sandwich board,the platform stage is longer and the energy absorption effect is improved.Combined with the test and the finite element,it is found that the reason for these two stages is that the ultimate load can cause the buckling deformation of the sandwich layer under the loading condition,thus reducing the internal voidage of the structure,and the structure is further loaded to the dense stage.The validity of the research results is verified by the comparison of the two,which provides guidance for the future design and application of metal rubber corrugated sandwich plate.
